ON/OFF setting from EIA-485 communications without regards to trigger logic switch, turned OFF at ‘0’ and ON at ‘1’. ON/OFF setting will not be held after turning the power off.
When operating EIA-485 communications and trigger signal input at same time in ON/OFF mode.
When Trigger logic switch is at HIGH: if ether controls setting to OFF setting, Light unit will be turned OFF
When Trigger logic switch is at LOW: if ether controls setting to ON setting, Light unit will be turned ON

Select the lighting mode form Continuous Mode, ON/OFF Mode, or Strobe Mode. The lighting time can be set in Strobe Mode.
(The Strobe Mode can be set for 24V DC Light Units only.) For details on the external trigger input, refer to 9. Inputting the External Trigger.
The light intensity is controlled to any of 256 levels. 000 to 255 (000: Minimum, 255: Maximum)

Digital window
Set value
Set the value to 00 to enter
Normal Mode and keep the Light
Unit lit continuously.
Set the value to 00 to enter ON/OFF Mode and turn the
Light Unit ON and OFF. The Light Units are turned ON or
OFF according to the external trigger signal input.
Select the lighting time from 01 to 10 (40 µs to 40 ms) to use a strobe light.
The Light Units are turned ON for the set time after the external trigger
signal is input. The Strobe Mode can be set for 24V DC Light Units only.
Continuous Mode
ON/OFF Mode
(If the external trigger is not used, the Light Units are ON continuously.)
Strobe Mode
(If an external trigger is not used, the Light Units are OFF.)
Four channels from L1 to L4 are allocated to the 24V LIGHT and HLV LIGHT output connectors. When L1 is selected, settings for the L1 Light Unit for the
24V LIGHT connectors and the HLV LIGHT connectors can be changed. The 4 channels can be controlled separately.
(Set values that are higher than 03 are not valid.)
